onds.
3. To cool the brake system, drive the vehicle at 50 km/h (31
MPH) for 1 minute without stopping.
4. Repeat steps 1 to 3, 10 times or more to complete the burnish-
ing procedure.

Bleeding Brake SystemNJBR0009CAUTION:
+Carefully monitor brake fluid level at master cylinder dur-
ing bleeding operation.
+Fill reservoir with new brake fluid ªDOT 4º. Make sure it is
full at all times while bleeding air out of system.
+Place a container under master cylinder to avoid spillage
of brake fluid.
+For models with ABS, turn ignition switch OFF and dis-
connect ABS actuator connectors or battery ground cable.

1. Connect a transparent vinyl tube to air bleeder valve.
2. Fully depress brake pedal several times.
3. With brake pedal depressed, open air bleeder valve to release
air.
4. Close air bleeder valve.
5. Release brake pedal slowly.
6. Repeat steps 2. through 5. until clear brake fluid comes out of

Brake Burnishing Procedure (Cont'd)
BR-9

PurposeNJBR0082The ABS consists of electronic and hydraulic components. It allows for control of braking force so that lock-
ing of the wheels can be avoided.
The ABS:
1) Ensures proper tracking performance through steering wheel operation.
2) Enables obstacles to be avoided through steering wheel operation.
3) Ensures vehicle stability by preventing flat spins.
ABS (Anti-Lock Brake System) OperationNJBR0083+When the vehicle speed is less than 10 km/h (6 MPH) this system does not work.
+The Anti-Lock Brake System (ABS) has self-test capabilities. The system turns on the ABS warning lamp
for 1 second after turning the ignition switch ON. The system performs another test the first time the vehicle
reaches 6 km/h (4 MPH). A mechanical noise may be heard as the ABS performs a self-test. This is a
normal part of the self-test feature. If a malfunction is found during this check, the ABS warning lamp will
come on.
+During ABS operation, a mechanical noise may be heard. This is a normal condition.

Self-diagnosis (Only Models with Data Link
Connector Terminal No. 9)
NJBR0091FUNCTIONNJBR0091S01+When a problem occurs in the ABS, the ABS warning lamp on
the instrument panel comes on. To start the self-diagnostic
results mode, ground the self-diagnostic (check) terminal
located on ªData link connectorº. The location of the malfunc-
tion is indicated by the ABS warning lamp flashing.
SELF-DIAGNOSIS PROCEDURENJBR0091S021. Drive vehicle over 30 km/h (19 MPH) for at least one minute.
2. Turn ignition switch ªOFFº.
SEF378Y
3. Ground terminal ª9º of ªData link connectorº with a suitable
harness.
4. Turn ignition switch ªONº while grounding terminal ª9º.
Do not depress brake pedal.
Do not start engine.
SBR759E
5. After 3.0 seconds, the ABS warning lamp starts flashing to
indicate the malfunction code No. (See NOTE.)
6. Verify the location of the malfunction with the malfunction code
chart. Refer to BR-76. Then make the necessary repairs fol-
lowing the diagnostic procedures.
7. After the malfunctions are repaired, erase the malfunction
codes stored in the control unit. Refer to BR-64.
8. Rerun the self-diagnostic results mode to verify that the mal-
function codes have been erased.
SEF378Y
9. Disconnect the check terminal from the ground. The self-diag-
nostic results mode is now complete.
10. Check ABS warning lamp for deactivation after driving vehicle
over 30 km/h (19 MPH) for at least one minute.
11. After making certain that ABS warning lamp does not come on,
test the ABS SELF-DIAGNOSIS in a safe area to verify that it
functions properly.
NOTE:
The indication terminates after five minutes.
However, when the ignition switch is turned from ªOFFº to ªONº, the
indication starts flashing again.
